' 2 Claims. C1. 20-52 This invention relates in general to windows and in particular to sashless windows wherein the window panes Un d S te at are slideable horizontally to open and closed positions.

seal when the window panes are in the closed position.

When. the panes are slid horizontally to the open position it is obvious that the panes will rub together and should there be any small particles of grit or the like between the panes, the surface of the window panes will be scratched and marred. i i i In additionthe locking means forrwindows of this type comprises, generally a swing type oflock that is fastened to one of thewindow panes by a hole drilled therethrough and it is virtually impossible to construct such device so that the fastening bolt is flush with the surface of the window pane. In numerous cases when the window is slid to the open position this protruding bolt has struck against the other window pane with suflicient force to crack the window pane.

It is the principal object therefore to provide a sashless window having horizontally slideable window panes with means for guiding the window panes apart when slid to the open position.

A second object is to provide a sashless window wherein the horizontally sliding window panes are guided together when slid to the closed position.

A still further object is to provide a sashless window with nothing protruding from the panes to strike against other panes.

An additional object is to provide a sashless window having an improved window locking mechanism.

Additional objects and advantages of my construction will be obvious to those skilled in the art on reading the following specification in the light of the attached drawings. It must be understood that the information disclosed therein is by way of example and illustration only and is not to be construed as a limitation. The invention herein is to be limited only by the terms of the appended claims and by the prior art.

Figure 13 is an end View as would be seen at the lines 1313 in Figures 9 and 10.

Figure 14 is an enlarged broken away end view showing inside and outside sashless windows together with the window sill and the window track drainage system.

Figure 15 is a view as seen at the line 1515 in Figure 14. l

Figure 16'i s a broken away view as seen at the line 1'6 16in Figure 1 My window comprises a window frame designated generally by the numeral 1 and containing therein the fixed window pane 2 and sliding window pane 3 which,

as is common, are fitted in tracks in the window frame 'to operate horizontally slidably therein from the closed position"a's illustrated in Figure l in the drawings to the partially open position as illustrated in Figure 3 or "t'o the' fully open""position if desired.

It will be noted in Figure 1 in the drawings that the window panes 2 and 3 are partially overlapped as indicated at 4 when the windows are in the closed position and that the window overlap increases as shown in Figure 3 as the moveable window pane 3 is slid to the open position.

With the window panes 2 and 3 in the closed position as illustrated in Figure l in the drawings it is necessary that the overlapped portions at 4 fit tightly together and, if possible, provide a weather tight seal. To accomplish this, prior constructions have formed the horizontal window tracks as closely together as possible to provide a nearly weather tight fit at the overlapped portions 4. This construction, however, has resulted in the panes 2 and 3 remaining in close contact when the pane 3 is slid to the open position as illustrated in Figure 3 with the result that the surfaces of the panes 2 and 3 may be scratched by any abrasive substances that may be lodged therebetween.

In place of the parallel window tracks for the lower edges of the window panes 2 and 3 as would be found in present day construction, I have provided tracks for the lower edge of the window panes 2 and 3 whereby the window pane 3 is deflected away from the pane 2 as the window pane 3 is moved to the open position and whereby the window pane 3 is guided into close contact with the window pane 2 at the lapped portion 4 when the window pane 3 is moved to the closed position.

The window pane 2 is contained in the track 9 which extends past the edge of the pane 2 as indicated at 17 in Figure 9 in the drawings to permit movement of the pane 2 and allow its removal for cleaning or replacement. In the embodiment illustrated, the track 9 is parallelto the track 14 and separated therefrom by the ridge 16 as seen best in Figure 11 in the drawing. The ridge 16 tapers to a point 18 which is slanted away from the window pane 2 as indicated at 19.

The window pane 3, in the closed position, is contained in the track 20 which is sloped as indicated at 21 22 of the window pane 3 will be guided by the point 18 onto the sloping surface 19 and into the track 14 away from the window pane 2. When the window pane 3 is moved from the open to the closed position the opposite edge 23 of the window pane 3 will come into contact with the sloping surface 21 toguide the window pane 3 into the track 20 and ensure that the lapped portions 4 -of the windows 2 and 3 will be in close contact.

As stated previously it has been the practice heretofore ;to provide a lock for this type of window in the form of a catch attached to the moveable window pane 3 through a hole drilled in the window pane and engageable with a hook or other suitable device attached to the window frame 1. To overcome the necessity of drilling holes in the glass and to provide a more efficient and easily manipulated lock I have developed the lock indicated in Figure 16 in the drawings. My improved lock comprises the member 26 which is seated on the spring 27 in the window sill 25 to operate through the opening 28 in the window track member 24. The opening .28 is positioned immediately forward of the window pane 3 so that the spring 27 will force the member 26 into the path of the window 3 when the window is in the closed position. To release the lock, the member 26 is pressed downwardly manually and the window pane 3 is slid to the open position over the member 26 thereby maintaining the member 26 in the depressed position. The member 26 is maintained in the opening 28 against the action of the spring 27 by the shoulder 29 which engages with the bottom of the opening 28 in the window track 24. Manipulation of the window pane 3 is facilitated by the handle 30 which is attached to the window pane 3 by any well known means.

Drainage from the window tracks 9, 14 and 20 is provided by the channel 31 which is joined to the window tracks by the ducts 32. While only one channel 31 is shown it will be obvious that additional channels and ducts would be provided as required.

What I claim as my invention is:

1. In a sashless window having a window frame with a first groove in the frame arranged to receive a stationary window pane and a second groove arranged to receive a movable window pane in partially overlapped relationship with the said stationary window pane when in the closed position, an angular bottom in the said second groove sloping toward the stationary window pane and adapted to maintain the said partially overlapped portions tightly together, a third groove alongside the said first groove, a ridge between the said first and third grooves terminating in a point in the second groove to deflect the movable window pane into the third groove when the said movable window pane is moved from the closed to the open position.

2. In a sashless window as claimed in claim 1, a lock comprising a manually operable spring loaded stop positioned in the said second groove to project into the path of the movable window pane and to engage with the lower corner of the said movable window pane.
